Your safety and the safety of others is very important. We have provided many important safety
messages in this manual. Please read these messages carefully.
A safety message alerts you to potential hazards that could hurt you or others. Each safety message is
associated with a safety alert symbol. These symbols are found in the manual and inside the
instrument. The definition of these symbols is described below:
General Warning/Caution: Refer to the instructions for details on the specific danger.
Hot Surface Warning
Electrical Shock Hazard
Technician Symbol: All operations marked with this symbol are to be performed by
qualified maintenance personnel only.
Electrical Ground: This symbol inside the instrument marks the central safety grounding
point for the instrument.
CAUTION
The analyzer should only be used for the purpose and in the manner
described in this manual.
If you use the analyzer in a manner other than that for which it was
intended, unpredictable behavior could ensue with possibly hazardous
consequences.

1.0 Getting Started
The M501Y has been designed to operate with the M200EU low level NOx analyzer.
1.1 Unpacking
1. The M200EU with NOy Option comes in three boxes.
• The M200EU analyzer
• The Bypass Pump Chassis
• The External Converter and umbilical cable assembly
2. Verify that there is no apparent shipping damage. If damage has occurred please advise shipper
first, then API.
To avoid personal injury, always use two persons to lift and
carry the Model 501 Pump Pack Chassis.
CAUTION
3. Before operation of the M200EU, remove the shipping screws as shown in the M200E/EU Manual.
4. Please check the voltage and frequency label on the rear panel of the instrument for compatibility
with the local power before plugging in the M501Y.
1.2 Electrical and Pneumatic Connections
1. Mount the converter on a suitable mast outside of the enclosure.
2. Route the umbilical cable assembly into the shelter.
3. Locate the M200EU and M501Y Bypass Pump Chassis in close proximity, preferably mounting
one over the other in a 19” rack.
4. Connect the electrical/pneumatic cable fittings to the rear of the Bypass Pump Chassis. Use the
tags on each tube and Figure 1.1 to match up the correct tube with the rear panel bulkhead fitting.
Please note that the dashed lines show optional Zero/Span Valve configuration connections.
5. Connect the 7-pin power and signal cable to the connector on the rear of the Bypass Pump Chassis.
6. Connect the power cord to the correct line voltage.
WARNING
• Lethal voltages are present inside case
• Do not operate with cover off during normal operation

1.3 Initial Operation
1. After confirming proper supply voltage, turn on the instrument power. If you are unfamiliar with
the M200EU with NOy Option, we recommend that you read the overview in Section 3 before
proceeding.
2. The power indicator light and display should immediately light, in addition the bypass pump
should start up. The M501Y requires about 30 minutes for the converter to come up to
temperature.
3. While the converter is coming up to temperature, the M200EU should be powered-up also. Follow
the instructions in the M200E/EU Manual to confirm proper operation of that instrument. Note: It
will take 30 minutes for the ozone generator to start up in the M200EU. During that time the
instrument will not respond to span gas.
4. After 30 min, the display on the Bypass Pump Chassis should read 315
converter is up to temperature.
5. Proceed to Section 4 of this manual to do a zero/span check.
